Frequently Asked Questions

What is the OSG Spiral Point Tap M8x1.25 used for?

The OSG Spiral Point Tap M8x1.25 is used for threading blind or through holes in metal, particularly in production environments. Its spiral-point design pushes chips forward, reducing clogging. It is suitable for general-purpose tapping in materials like steel and aluminum, commonly used in automotive and manufacturing industries.

What are the specifications of the OSG Spiral Point Tap MPN 15431?

The OSG Spiral Point Tap MPN 15431 has a metric M8x1.25 thread size, OH2 / 6H tolerance class, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and is designed for general-purpose tapping. The OH2 / 6H specification indicates a precision ground thread form for consistent fit.

Where to buy the OSG Spiral Point Tap M8x1.25 worldwide?

You can source the OSG Spiral Point Tap M8x1.25 worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we provide reliable sourcing for this OSG tap and other industrial tooling.

How to select the correct OSG tap for threading applications?

To select the correct OSG tap, match the thread size (e.g., M8x1.25) and tolerance class (e.g., OH2 / 6H) to your workpiece material and hole type. For through holes, a spiral-point tap like this OSG model pushes chips ahead. For blind holes, consider spiral-flute taps. Always use proper cutting fluid and follow manufacturer speed recommendations.
